Trials of Joan of Arc essays

Trials of Joan of Arc essays Jeanne dArc, better known as Joan of Arc, was the Maid of Orleans. She was a great heroin of the Hundred Years War for the French and was the spirit of the army. She was only a teenager when she heard the voices of Saint Catherine, Saint Michael, and Saint Margaret. The voices told her to march with the French army to drive out the English and place Charles VII on the throne. She provided support and spirit to the troops and shaped them up into better soldiers. She had successful victories like Orleans and at Patay, but was defeated and captured by the Burgandians while defending Compiegne. The Burgundians sold her to the English who had long been after her. She would be tried for witchcraft and heresy by the ecclesiastical court of Rouen led by Bishop Pierre Cauchon. The court was judged by the Bishop along with his assessors. The trial consisted of six public examinations, 9 private examinations, and several readings of articles. In the first public examination, Jeanne made it clear to the bishop and the forty-two assessors present that she would only tell the things she was allowed to tell even if it meant death upon her own oath instead of what the English wished her to. "Of my father and my mother and of what I did after taking the road to France, willingly will I swear; but of the revelations which have come to me from God, to no one will I speak or reveal them, save only to Charles my King; and to you I will not reveal them, even if it cost me my head; because I have received them in visions and by secret counsel, and am forbidden to reveal them. Before eight days are gone, I shall know if I may reveal them to you." The English interrogated her until she revealed the names of herself, her father and mother and of her birthplace alon g with many other personal questions. At the second public examination, Jeanne was asked to swear an oath again to which she claimed, I made oath to ...

Candy Coffee Filter Chromatography

Candy Coffee Filter Chromatography You can do paper chromatography using a coffee filter to separate the pigments in colored candies, like Skittles or MM candy. This is a safe home experiment, great for all ages. Difficulty: Easy Time Required: about an hour Candy Chromatography Materials Basically, you need colored candies, a coffee filter or other porous paper, and salt water for this project. Skittles or MM candiesCoffee filterTall glassWaterTable saltPencilToothpicksPlate or foilPitcher or empty 2-liter bottleMeasuring cups/spoons Procedure Coffee filters usually are round, but its easier to compare your results if the paper is square. So, your first task is to cut the coffee filter into a square. Measure and cut a 3x3 (8x8 cm) square from a coffee filter.Using a pencil (ink from a pen would run, so pencil is better), draw a line 1/2 (1 cm) from the edge of one side of the paper.Make six pencil dots (or however many colors of candy you have) along this line, about 1/4 (0.5 cm) apart. Underneath each dot, label the color of the candy you will test on that spot. You wont have space to write the whole color name. Try B for blue, G for green, or something equally easy.Space 6 drops of water (or however many colors you are testing) equally distant on a plate or piece of foil. Position one candy of each color on the drops. Give the color about a minute to come off into the water. Pick up the candy and eat it or throw it away.Dip a toothpick into a color and dab the color onto the pencil dot for that color. Use a clean toothpi ck for each color. Try to keep each dot as small as possible. Allow the filter paper to dry, then go back and add more color to each dot, a total of three times, so you have lots of pigment in each sample. When the paper is dry, fold it in half with the color sample dots on the bottom. Ultimately, you are going to stand this paper up in a salt solution (with the liquid level lower than the dots) and capillary action is going to draw the liquid up the paper, through the dots, and toward the upper edge of the paper. The pigments will become separated as the liquid moves.Prepare the salt solution by mixing 1/8 teaspoon of salt and three cups of water (or 1 cm3 of salt and 1 liter of water) in a clean pitcher or 2-liter bottle. Stir or shake the solution until it is dissolved. This will produce a 1% salt solution.Pour the salt solution into a clean tall glass so that the liquid level is 1/4 (0.5 cm). You want the level to be below the sample dots. You can check this by holding the paper up against the outside of the glass. Pour out a little salt solution if the level is too high. Once the level is correct, stand the filter paper inside the glass, with the dot side down and the edge of the paper wetted by the salt solution. Capillary action will draw the salt solution up the paper. As it passes through the dots, it will begin to separate the dyes. You will notice some candy colors contain more than one dye. The dyes separate because some dyes are more likely to stick to the paper, while other dyes have a higher affinity for the salt water. In paper chromatography, the paper is called the stationary phase and the liquid (salt water) is called the mobile phase.When the salt water is 1/4 (0.5 cm) from the top edge of the paper, remove it from the glass and place it on a clean, flat surface to dry.When the coffee filter is dry, compare the results of chromatography for the different candy colors. Which candies contained the same dyes? These are the candies that have corresponding bands of color. Which candies contained multiple dyes? These are the candies that had more than one band of color. Can you match any of the colors with the names of the dyes listed on the ingredients for the candies? Further Experimentation: You can try this experiment with markers, food coloring, and powdered drink mixes. You can compare the same color of different candies, too. Do you think the pigments in green MMs and green Skittles are the same? How can you use paper chromatography to find the answer?What do you expect to happen if you use a different type of paper, such as a paper towel or a different brand of coffee filter? How do you explain the results?
